Ok so I didn't give up on this board yet. Woke up and decided I would keep trying with it. Despite it being a huge pain in the ass, I actually have 4920 MHz stable. Bumped it up to 5 ghz and im testing stability now. Voltage is 1.572 V idle and that goes to 1.6 under load which is high, so I won't increase that anymore. Temps are fine, although I am going to try to get a thermocouple on the VRM heatsink this week if I keep this board to see what it gets to.
Edit again: If I keep this board this is my stable 24/7 overclock: http://valid.canardpc.com/2769732
Temps never get over 48 C with the kraken x60 and my custom fan profile.
